Alstroemeria plant named ‘Pandora’

ABSTRACT

A new and distinct cultivar of  Alstroemeria  plant named Pandora, characterized by its upright and strong flowering stems; durable and long-lasting leaves; freely flowering habit; red purple and yellow-colored flowers; and good postproduction longevity.

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: Pandora.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a cut flower Alstroemeria, and hereinafter referred to by the name Pandora.

The new Alstroemeria is a product of a planned breeding program conducted by the Inventor in Wateringen, The Netherlands. The objective of the breeding program was to develop new cut flower Alstroemeria cultivars with freely flowering habit, large flowers, attractive flower colors and excellent postproduction longevity.

The new Alstroemeria originated from a cross-pollination made by the Inventor in Wateringen, The Netherlands, in 1999 of a selection of Alstroemeria hybrida identified as code number 211-6, not patented, as the female, or seed, parent with a Alstroemeria hybrida selection identified as code number 201-3, not patented, as the male, or pollen, parent. The new Alstroemeria was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Wateringen, The Netherlands in 1999.

Asexual reproduction of the new cultivar by tissue culture in a controlled environment in Wateringen, The Netherlands, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of the cultivar Pandora have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of Pandora. These characteristics in combination distinguish Pandora as a new and distinct cultivar:

-   -   1. Upright and strong flowering stems.     -   2. Durable and long-lasting leaves.     -   3. Freely flowering habit.     -   4. Large red purple-colored flowers.     -   5. Good postproduction longevity.

Plants of the new Alstroemeria can be compared to plants of the parent selections. Plants of the new Alstroemeria are more freely flowering than plants of the parent selections. In addition, plants of the new Alstroemeria and the parent selections differ in flower color.

Plants of the new Alstroemeria can also be compared to plants of the cultivar Maestro, disclosed in a U.S. Plant patent application Ser. No. 11/177,973 filed concurrently. In side-by-side comparisons conducted in Geldern, Germany, plants of the new Alstroemeria differed from plants of the cultivar Maestro in the following characteristics:

-   -   1. Plants of the new Alstroemeria had longer flowering stems         than plants of the cultivar Maestro.     -   2. Plants of the new Alstroemeria had smaller inflorescences and         smaller flowers than plants of the cultivar Maestro.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Alstroemeria, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering stem of Pandora grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flower and leaves of Pandora.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants of the new Alstroemeria grown during the spring in ground beds in Geldern, Germany in a glass-covered greenhouse for about five months. During the production of the plants, day temperatures were about 11° C. and night temperatures were about 7° C.
